Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Detailed Description

The purpose of this clinical research study is to evaluate the feasibility of the GT Metabolic Solutions Magnet System, GJ Biofragmentable ("MagGJ System") for creation of a side-to-side anastomosis for gastro-ileal or gastro-jejunal diversion in obese adults. This partial diversion of intestinal contents from the stomach to the ileum or jejunum is intended to facilitate weight management/loss in obese adults and improve metabolic outcomes in obese adults with type 2 diabetes mellitus ("T2DM"). Side-by-side anastomoses are currently created by sutures, staples, and anastomotic compression devices. A predicate procedure is the single anastomosis sleeve ileal (SASI) bypass procedure that includes a gastro-ileostomy at the distal antrum of the stomach. Additionally, the one anastomosis gastric bypass (OAGB) or single anastomosis gastric bypass (SAGB) performed in two stages may also be considered a predicate procedure where an anastomosis between the jejunum and anterior lesser curvature of the stomach is performed, followed by a second stage gastric pouch stapling more than 12 months later (non-study procedure).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
35

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • BMI 35-50 kg/m2, inclusive without previous sleeve gastrectomy, and where (A) Gastro-jejunal diversion is indicated for the first stage, of a 2-stage, one anastomosis gastric bypass (OAGB), or (B) Single anastomosis gastric bypass (SAGB), with the second stage gastric pouch stapling performed >12 months after the gastro-ileal diversion, and not part of the investigational study
